UNITED STATES PATENT OFFICE.

AXEL S. VOG'I, OF ALTOONA, PENNSYLVANIA.

ENGINE CROSS-HEAD.

SPECIFCATION forming part of Letters Patent No. 450,830, dated April 21, 1891.

Application tiled April 2]., 1890. Serial No.348,799. (No model.)

To a/ZZ whom it' may concern.:

Be it known that I, AXEL S. VOGT, a subject of the King of Sweden, and a resident of Altoona, county of Blair, State of Pennsylvania, have invented a certain new and useful Improvement in Guides for Engine Crossd'leads, of which the followingis a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to the devices used for guiding the cross-head of an engine, and particularly the guides for locomotive crossheads, the object being to improve the construction of such guides, making them at the same time more simple and stronger than has heretofore generally been the case.

The nature of myimprovement will be best understood as described in connection with the drawings in which it is illustrated, and the novel features which I desire to protect by Letters Patent are hereinafter clearly set forth in the claims.

Reference being now had to the drawings which illustrate my invention, Figure 1 is an elevation showing my improved cross-head guide, together with the parts of a locomotiveengine to which it is attached, and the crosshead moving in said guide. Fig. 2 is a plan view of the cross head guide. Fig. 3 is a cross-sectional View on the line oc 0c of Fig. l. Fig. 4 is a cross-sectional viewon the line ze of Fig. 1. Fig. 5 is a plan view of the crosshead. Fig. 6 is a side elevation of the crosshead on the sectionline 1U w of Fig. 5, and Fig. A is a view showing amodiiicat-ion of my improved cross-head guide.

A indicates the end of the locomotive-cylinder.

B is a part of the frame of the locomotive known as the yoke.

C is the pistonrod.

D is the cross-head, d being a socket to receive the end of the piston-rod C, and d a bearing formed in the orosshead to receive the pin of the 4connecting-rod. nd2 is the guiding portion of the cross-head, do a shoe or slipper secured to the upper face of the guiding portion d2, and d* d* similar slippers or shoes secured to the lower faces of the guiding por tion of the cross-head.

E is the cross-head guide, which I make, as shown, of two L-shaped sections E E', the long arms e e of which are abutted against each other and secured together by bolts F F, tbc. rlhese sections E consist, essentially, of the long arms c e, the downwardly-extending portions e e', and the .inwardlyextending ends e2 e2, which extend toward each other, their inner surface being horizontal and parallel to the inner surface of the long arms ee. These parallel surfaces form the guiding-surfaces against the slippers d3 ebd'1 of the crosshead rest, the portion cl2 of the cross-head and the standard connectingitwith the cross` head proper being inclosed in the T-shaped recess formed between the sections E E.

In order to st-renthen the cross-head guide, I form on the outer portion of the long arms e e a strengthening-rib e3. Preferably the rib is formed at the inner extremity of the arm e, so that when the two sections E are secured together the ribs will also abut against each other, as shown in Figs. l to 4; but the strengthening-ribs e3 may be formed on any portion of the long arms e, and in Fig. I have shown them as formed at the outer extremity of the arms.

Having now described my invention, what I claim as new, and desire to protect by Letters Patent, is

l. A cross-head guide E, consisting of two L-shaped sections E E', secured together with their long arms abutting against each other, as described, and so as to form a T-shaped recess to receive the guiding portion of the cross-head and aiford bearings for its upper and lower bearing-surfaces. 1

2. Acrosshead guide E, consisting of two L-shaped sections E E', having bearing-ribs e3 formed on the outside of their long arms, said sections being secured together with their long arms abutting against each other, as described, and so as to form a T`-shaped recess to receive the guiding portion of a cross-head and afford bearings for its upper and lower bearing-surfaces.
